A reinforced concrete threaded pile provides a generally conically shaped tapered concrete pile member which is provided with a metallic reinforcement core for carrying the torsional and tensile forces created in the pile during its insertion. A metallic head is provided at, for example, the upper portion of the pile, which provides a point for the connection of a sufficient torsional driving force thereto for insertion of the pile. The head member can be metallic, and is substantially integrally connected to the reinforcement core, so that the torsional forces can be developed through the head and the reinforcement core such that torsional and tensile forces are not carried by the concrete to a degree which would cause a failure of the concrete by cracking. The concrete body is provided with an outer surface of spiral threads which has a relatively minor thread pitch that provides for relatively easy insertion of the pile into the desired soil medium and is mechanically compatible therewith. If desired, reinforcement can be provided in the threads. The threads are equally spaced, and a female "soil socket" is formed upon insertion of the pile into the earth, the spiral tapered pile gradually expanding and compacting the surrounding soil as the equally spaced threads push the pile downward.
